One person was killed and six were injured in an attack on the offices of an international charity in the centre of the Afghan capital, Kabul.
A suicide bomber targeted the humanitarian organisation Care in the Shar-e-Naw area and gunmen then stormed the building, Tolo News TV reported.
After hours of gunfight, security forces killed all insurgents, said Ministry of Interior spokesman Sediq Sediqqi.
"Forty-two people including 10 foreigners were rescued," Sediqqi said on Twitter.
The attack started with a car bomb that ripped through the city. Gunmen then reportedly stormed the building.
Earlier, a series of blasts left at least 24 people dead and nearly 100 others wounded.
An army general and two senior police officers were among the dead from those attacks, a ministry of defence spokesperson told the BBC.
The Taliban, who have carried out frequent attacks in Kabul, said they were responsible for the blasts.
